DAMAGE ANALYSIS OF EMBANKMENT SLOPE BASED ON FLUID PHYSICAL PARAMETERS AND SCOURING INTENSITY

As an important construction structure of human production and life, embankment structure has many functions. The damage of embankment is a serious threat to the safety of human property and life, so it is important to research the damage factors and how to reduce the damages. This paper focuses on the influences of design structure and other factors on embankment slope damage and ecological environment in most existing water conservancy and hydropower projects, based on ecological environment protection and damage degree of embankment slope, a coupling model of embankment damage degree and environmental protection efficiency is constructed to explore the impact of different factors on embankment damage degree and ecological environment pollution, at the same time, the relationship of reinforced embankment with promoting ability of protection to the ecological environment and people's life and property safety is also researched. The results show through the coupling model, the factors of reduce embankment damage can be found in perspective of sustainable development and according to the different paraments such as fluid physical parameters and scouring intensity, the effective measures and solutions to alleviate the damage and protect the embankment are explored. The results show the relation between the damage degree of embankment and the scouring strength of the fluid is positive correlation. When the impact force of the fluid reaches 7000N/m(2), the damage degree of embankment reaches 0.95, and the dike breach is easy to occur at this time, which is much higher than the 0.57 when the impact force is 6000N/m(2). The biodiversity of the ecosystem will be also greatly affected, decreasing from 25 species at 6000N/m(2) to 15 species at 7000N/m(2). Finding the measures and solutions to solve the embankment damage, not only to promote the safety of people's life and property, but also to alleviate the decrease rate of ecological environment biodiversity.
